I dunno about angering me, but there are little things that annoy me.
people insisting that any genre of music isn't music.
people insisting that all anime is the same.
people misusing the word "epic".
people saying "should of". It's should have, people. should have.
people saying "I could care less". No, you mean to say "I couldn't care less".
people saying "I'm OCD". You can't be OCD.
people saying that they think they might have OCD just because they have little quirks like always reloading in shooters even if they only used one or two bullets. That's nothing. You don't have OCD. Stop it.
